Application filed July .7, 1905. Serial No. 268,649.

To (LM w/wm it may concern:

Be it known that I, HUBERT WITTE, a citizen of the United States,residing in the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Reversible Oar-Seats, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming part of thisspecification.

My invention relates to that class of carseats commonly known aswalk-over seats, in which the seat-back is arranged to swing from sideto side of the seat, and the cushion is arranged to be tilted toproperly position it relatively to the seat-back in either position towhich it is shifted.

Figure I is an end elevation of my seat. Fig. II is a front elevation ofone end of the seat. Fig. III is a vertical cross-section. Fig.V

IV is a vertical longitudinal section taken on line IV IV, Fig. III.Fig. V is a horizontal section taken on line V V, Fig. III. Fig. VI is avertical cross-sectiontaken on line VI VI, Fig. V. Fig. VII is a similarview to Fig. III, showing the parts in the position assumed when theseat-back is in a reclined position. Fig. VIII is an elevation of thehandle of one of the rock-levers by which theback-supporting-arm-controlling means are actuated.

In the accompanying drawingsI have illustrated but one end of mycar-seat, and it will be understood that a description of said end will-apply equally t0 the other end of the seat.

1 designates the seat-legs, which are provided With arms 2, whichsupport the longitudinal rails 3, extending from end to end of the seat.y

5 represents uprights secured to the rails 3 at their ends and which aresurmounted by arm-rests 6.

7 designates the seat ends, which are secured to the longitudinal rails3, each of said seat ends being provided centrally at its upper edgewith a pocket 8, (see Figs. III to V, inclusive, and Fig. VIIL) thepurpose of which will hereinafter be explained.

9 designates the seat-cushion. This cushion is tiltingly supported uponrests 10, (see Figs. II and IV to. VI, inclusive,) which are looselyseated on the longitudinal rails 3, the rests bemember that serves totilt the rest,

ing preferably provided with dowels 11, that enter into the cushion atits lower side. Each rest has a yoke 12 provided with acentrallydisposed vertical slot 13, which receivesv a as willhereinafter appear.

141 designates the seat-back, and 15 represents back-supporting armspivoted at 16 to the end bars 17 of said back, as seen in Figs. I to IV,inclusive. The back-supporting arms are xed to a rock-shaft 18,journaled in the seat ends 7 as seen in Fig. IV. Each backsupporting armis enlarged at its lower end and contains a curved slot 15', and at thefront and rear of the enlargement of each arm are respectivelyextensions 15' and 15b. The slots 15 in the back-supporting arms receivestopstuds 7', projecting from the inside faces of the seatends 7, (seeFigs. III to V, inclusive, and Fig.VII,) the said stop-studs serving torestrict the movement of the back-supporting arms when they areswung'from side to side 'of the seat.

19 designates restraining-links for limiting the rocking motion of theseat-back. These links are pivoted at 2O to the back-supporting arms 15,and they have slot-and-pin connection at 21 with the lower ends of theseatback end bars 17, thereby permitting freedom of movement of theseat-back depending upon the restraining -links inner end of eachrestraining-link is a notch 22, that is adapted to receive the adjacentstopstud 7 when the seat-back is swung from side to side of the seat andfor the permission of which the back and its end bars and therestraining-links are moved into alinement with the back-supporting arms15 in order that said parts may be rocked as a unit from one side of theseat to the other side.

23 represents prongs or catch-teeth forming parts of therestraining-links 19 and with which said links terminate at their innerends at opposite sides of the central notches l22. These prongs areadapted to engage the stopstuds 7' when the seat-back is in a reclinedposition, as seen in Fig. VII, and by such engage- At the center of thement serve to hold the restraining-links from i.

IOO

24 designates a rock-shaft, the ends of which are journaled in the seatends 7, as seen inL Fig. IV.

25 is a link fixed to the rock-shaft 24 and extending upwardlytherefrom. 'Ihis link has pivoted to it at 26 a dog-carrying bar 27,which terminates at its ends in dogs 28, extending laterally toward theseat ends 7 and adapted to be moved into the path of travel of thebacksupporting-arm extensions 15 and 15b. Beneath the dogs 28 are ledges29 on which the dogs are adapted to rest under certain conditions. Theseledges are preferably integral with the seat ends 7.

30 designates a hand-lever at one end of the seat, which may, ifdesired, be duplicated at the other end. This hand-lever is fixed to therock-shaft 24 and extends upwardly within a space provided therefor inone of the seat ends, as seen most clearly in Fig. IV. The hand-leverhas pivoted to its upper end at 31 a handle 32, that is provided at itslower side with a pair of tongues 33, located at opposite sides of thepoint of pivotal connection of the handle to the lever. The tongues 33are adapted to occupy the pocket 8, hereinbefore mentioned, in the seatend 7. The point of pivotal connection of the handle to the lever 30 issuiiciently above the pocket 8 to permit of said handle being rocked inthe pocket in order that the tongue 33 at either end of the handle maybe rocked out of the pocket and the hand-lever be rocked in a directiontoward that end of the handle bearing the tongue when it is moved fromthe pocket. It will be seen that the tongues 33 thus serve to hold thehand-lever 30 from movement, due to their fitting in the pocket 8 untilthe leverhandle is rocked to free the lever, as stated.

When the hand-lever 30 is rocked in either direction, rotation isimparted to the rockshaft 24 and the link 25 is rocked to carry thedog-carrying bar 27 transversely of the seat. When the seat-back 14 isin upright position, the dog-carrying bars normally occupy the positionsseen in Figs. III and IV, at which time the hand-lever 30 is in verticalposition and is so held from movement by the seating of its handle inthe seatpocket 8. With the dog-carrying bar in this position the dogs 28at the ends of said bar, located at the sides of the seat at which theseat-back is positioned, rest upon the ledges 29 beneath them, which areprovided for their support,

and the adjacent extensions of the back-supporting arms rest upon saiddogs to support the arms without the ends of the slots 15 therein beingbrought to the stop-studs 7'. With the parts in the position describedthe seat-back may be shifted to the opposite side of the seat by rockingitV and its su pportingarms 15, and when this is done the extensions atthe edges of the back-supporting arms I ported by said seat which wereformerly foremost are moved to the previously free dogs 28 of the bar27, thereby depressing said dogs and causing them to rest upon theledges beneath them to sustain the back-supporting arms. When it isdesired to lower the seat-back into a reclined position, as seen in Fig.VII, the handle 32 of the hand-lever 30 is rocked so that its tongues 33may move out of the pocket 8 in the seat end which they previouslyoccupied. The said hand-lever may then be rocked in the direction inwhich the back-supporting arms are to be moved toY lower the seatback.As the hand -lever is so moved the rock-shaft 24 and link 25 arerotated, with the result that the dogs previously positioned beneath theextensions 15b or 15L of the backsupporting arms are shifted laterallyto move them from beneath the supporting-arm extensions, as seen in Fig.VII, thereby allowing rocking of the back-supporting arms to the extremelimit permitted by the stop-studs 7', operating in the slots of saidarms.

The cushion-rests 10 are rocked to tilt the cushion when the seat-backis moved from side to side through the following means: 34 is one of thepair of lever-arms fixed to the roc -shaft 18 and provided with'anelongated opening 35, through which the rock-shaft 24 passes, the saidopening being provided merely for the purpose of permitting movement ofthe lever-arm both above and below said rockshaft 24 withoutinterference with it. Each of the lever-arms 34 is provided with a stud36, that operates in the slot 13 of the cushion-rest yoke 12. IVhen theseat-back is swung from side to side and the back-supporting arms 15 aremoved therewith, rotation is imparted to the rock-shaft 18, and as aconsequence of this rotation the lever arms 24 are rocked, causing theirlower ends to be thrown in a direction the reverse `of the direction ofmovement of the back and its supporting-arms, whereby the cushion-restsare tilted, due to the operation of the lever-arm studs in the slot ofthe cushion-rest yokes.
